Fold 1/2 cup black beans, 1 tablespoon salsa, and 1 slice cheddar cheese in a small flour tortilla. Cook in a dry nonstick pan until the cheese is melted and tortilla is lightly browned. Then wrap it in foil and stick in a plastic baggie for easy transport.
The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the cecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts â ascending, transverse, descending and sigmoid. These sections form an arch, which encircles the small intestine.
The sigmoid colon is a curved, S-shaped region of the large intestine and is the final segment of the colon. It transports fecal matter from the descending colon to the rectum and anus. Feces are stored in the sigmoid colon until they are ready to be eliminated from the body through the anal canal.
